Title: Process for growing polycrystalline silicon crystal
Inventor: NAKAI YASUO
IPC: H01L21/208
Filed: 1982-04-22
Abstract: PURPOSE:To enlarge the particle diameter of polycrystalline silicon crystal and to grow it at relatively low temperature, and to obtain crystal having large particle diameter easily in a short time, by annealing polycrystalline crystal on a base, which is brought into contact with single crystal silicon. CONSTITUTION:In a state wherein the polycrystalline silicon 3 set on the base 2 such as glass, ceramic, etc. is brought into contact with the single crystal silicon 1 at the end, the polycrystalline silicon 3 is irradiated with the laser beam 4 so that it is annealed. Consequently, crystal grains having about 7-8mum or more particle diameters can be obtained easily in a short time at relatively low temperature of about 500-600 deg.C base temperature. Even if glass is used as the base, the polycrystalline silicon can be annealed at <= the temperature of the thermal shock resistance. The annealing can be carried out thermally and by electron rays alike. The injection of silicon ion into the polycrystalline silicon before annealing can further promote the enlargement and growth of crystal grains.

Title: Method for forming pattern of semiconductor device
Inventor: ONODA HIROSHI
IPC: H01L21/302
Filed: 1983-04-20
Abstract: PURPOSE:To accurately form a pattern without producing dimensional conversion difference by selectively emitting an accumulated layer and altering the etching velocity. CONSTITUTION:Radiation 13 of a laser light or the like is selectively emitted to a passivation film 12 in accordance with the prescribed pattern. At this time, the part 14 emitted by the radiation 13 of the film 12 is equivalently heat treated to increase the denseness of the part 14. As a result, a difference occurs at the etching velocity between the part 14 emitted by the radiation 13 and the part 15 not emitted, and the etching velocity of the latter becomes one/several tens of that of the former. Accordingly, when the film 12 is etched after the emitting, the part 14 remains, while the part 15 is removed by etching. As a result, the pattern of the film 12 is completely formed.

Title: Thin film etching
Inventor: SHINPO MASAFUMI
IPC: H01L21/302
Filed: 1987-03-23
Abstract: PURPOSE:To provide a multilayer interconnection with a good yield rate, by alternately performing a step, in which anisotropic etching is dominant, and a second step, in which etching is hardly carried out and a deposition of a second thin film is dominant, obliquely etching the second thin film, and tapering the side surface of the thin film. CONSTITUTION:An Al film 2 undergoes reactive ion etching by using CL gas, and the side surface of the Al film 2 is made nearly vertical. SiH4 and N20 are introduced, and an oxide film 4 is deposited on the entire surface as a second thin film. When anisotropic etching is performed by CL gas, the oxide film 4 is removed except the side surface of the Al film 2. The oxide film spacer 4 is made to remain. When the anisotropic etching is continued, the film 2 is etched with the spacer 4 as a mask. When this cycle is repeated by several times, the side surface of the Al film 2 becomes a staircase shape. When resist 3 is removed, the Al film 2 becomes the staircase shape and the oxide film 4 becomes tapered shape. Thus a multilayer interconnection is provided with a good yield rate.

Title: Data processor
Inventor: MIYAKI JUNJI

Filed: 1989-03-20
Abstract: PURPOSE:To improve the access efficiency of a CPU to a graphic memory GM by performing an indirect access to a local memory via a 1st bus master device when a 2nd bus master device has an access to the local memory. CONSTITUTION:When a 2nd bus master device 2 has an access to a local memory 3, the device 2 has an indirect access to the memory 3 via a 1st bus master device 1. That is, the switching time is omitted between both devices 1 and 2 because the access information received from the device 2 is temporarily stored in a store device of the device 1. Thus it is possible to decrease the control circuits and wirings which are required for transfer of data due to a switching operation and to improve the access efficiency of the device 2 to the memory 3 (GM).

IPC: H01J25/10
Filed: 1982-04-26
Abstract: PURPOSE:To eliminate an unstable phenomenon and obtain high conversion efficiency by making the magnetic flux density distribution on the electron beam passage of the focussing magnetic field to the distribution abruptly decreasing from a position slightly upstream the center of an output cavity gap to a collector side so as to improve the high frequency coupling between the output cavity and the electron beam. CONSTITUTION:An auxiliary magnetic pole plate 71 is coupled magnetically at the periphery of a magnetic pole plate 40 provided near a collector section 38, and a magnetic flux diffusion member 50 is coupled magnetically at the rear of the magnetic pole plate 40. The magnetic flux diffusion member 50 is made of a ferromagnetic material provided with a flange section 73 expanding outward in one body at the lower end of a magnetic cylinder 51. The flange section 73 is located near an output cavity wall 55 and is a disc with a size smaller than the outer diameter of the cavity wall 55. Accordingly, the magnetic force line distribution and magnetic flux density distribution R are attained as shown in the figure. That is, the maximum magnetic flux density position is located at a position slightly upstream the center (g) of an output cavity gas, and the magnetic flux is diffused from there, thus reducing the magnetic flux density abruptly. Thereby, an occurrence of a return beam is suppressed and the high frequency coupling between the electron beam and the output cavity is improved.
